WASHING MACHINE.

Application filed September 7, 1923. Serial No. 661,503. 7

- The invention is primarily devised as a means for lubricating thevertical spindle of a rotary washing machine, and 1s em' bodied in aconstruction which permits the lubrieantto be applied at the lower endof the spindle and automatically fed upwardly 7 thereof so as tolubricate the said spindle throughout its entire area of contact withthe fixed tubular post in which it is mounted to rotate.

" The invention also embraces the loose arrangement of a sleeve upon thesaid fixed post, to permit rotation of thelatter when engaged by thefabrics being washed and prevent destruction of such fabrics understrains imposed by the dolly.

These and other details of construction will be hereinafter described,and the nov-' elty of the invention will be theap ended claim. In t edrawing:

pointed out in Figure 1 is a vertical sectional view.

not shown, at its upper end. Thespindle 11 is guided and supported forrotation in an elongated tubular post 12, which latter by means ofclamping nuts 13 and 14 is securely positioned'in the central bore ofthe bottom 10 of the tub. Gaskets or washers 15 and 15' through whichthe said st is passed are applied at the opposite sidgs of the botv tom10, and when the nuts 13 and 14 are screwed in position, a leak-proofconnection is made. At the same time the tubular post 12 is rigidlysecured in operative position.

A cap nut 16 is threaded upon the upper end of the post 12, a disc 17fixed upon the upper end of the spindle 12 resting upon the said capnut, and supporting the spindle in vertical position. The disc 17 isprovided upon its upper face with an eccentrlcally arranged pin 18 whichlatter is designed to receive thereon the .usual agitating dolly, and

to impart movement thereto in the rotation.

of the spindle. A fly wheel 19 is mounted on the'lower end of thespindle 11 at a point immediately below the bottom 10 of-the tub. Theextreme lower end of the said' spindle is connected by reducing gears tothe shaft of an electric motor, which may be conveniently mounted uponthe frame of the washing machine, and arranged so as to give movementsof continuous rotation to the spindle 11.

Near its opposite ends the spindle 11 is provided with circumferentialgrooves 20 and'20 for the reception-of packing rings 21,inter-positioned between the opposite ends of the tubular post 12 andthe clearance at the base of the threadedportions of the nuts 16 and 14.An elongated groove 22 extendlng circumf'erentially of the spindle 11,connects the annular rooves 20 and 20', such elongated, groove beingdesigned to effect vertical movement of lubricant applied to the spindle11 at the lower end of the groove 22, so as to efficiently lubricate thesurface of the said spindle at the points of its contact with thetubular post 12. The packing rings 21, before referred to limit themovement of the lubricant to the area desired.

' One side of the nut 14 at the under side of the bottom 10 of the'tubis bored for the reception of an. oil cap or grease cup 23, containingany suitable lubricant. The lower end of the post 12 is provided with anopening in alignment with the oil cap or grease cup so that thelubricant may flow from the latter into contact with the surface of therotating spindle exposed thereto. The best results are secured byforcing the feed of the lubricant, and it will be apparent that thoroughlubrication of the spindle is sev cured. The assembly of the parts issuch that thewater in the tub, although it may rise to the cap 16,cannot reach the interior of the tubular post 12, the packing ring 21 atthe upper end of the spindle serving the double purpose of retaining theoil and excluding the water.

The under side of the cap nut 16 and the upper side of the nut 13 areprovided with concentric seats 24 and 25 for the reception of a tubularsleeve 26 adapted to have free rotation about the fixed post 12. Thepurpose of this construction is to prevent strain upon the fabrics beinwashed, due to the pull thereon by the agitating dolly. In the absenceof such a freely sleeve, the fabrics would cling. to the fixed post andbe torn in the movements of the dolly. Modification in the arrangementof. the partsmay be made without, epa rtingfrom the spirit of myinvention. J

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States; is:

In a washing machine, a tubular post fixed in the bottom of the tubthereof, a spindle mounted for rotation in the said post, a recessed nutupon the post bearing against the bottom of the tub, recessed cap nutthreaded upon the upper end of the post, and a freely rotating sleevesurrounding the said post and confined between andseated in the recessesin the said nuts, such sleeve rotatable by the pull of the fabricsthereon during the operation of washing.

In testimony whereof, I have signed my name at Milwaukee, this 31st dayof August,

HENRY JOSEPH.
